AMD Ryzen 7 5705GE vs Intel Core Ultra 5 338H Comparison

The Verdict

The database comparison places the Intel Core Ultra 5 338H firmly ahead of the AMD Ryzen 7 5705GE in overall benchmark performance. The Intel chip records an average benchmark score of 33,989, placing it in the 84th percentile of all CPUs, while the AMD part shows a 50th percentile ranking with no recorded average score in the available data. The Ultra 5 338H sits within 0.3% of the Intel Core Ultra 7 165H and the Intel Core i7-12800HX, indicating it performs at a similar level to those established mobile processors. The Ryzen 7 5705GE, by contrast, has no benchmark entries in the database, meaning its measured performance cannot be directly quantified here.

Given the data, the Intel Core Ultra 5 338H is the clear choice for any workload that relies on raw processing throughput, especially multi-threaded tasks. Its 12 cores, 18 MB of shared L3 cache, and 136.5 GB/s memory bandwidth position it as a capable mobile part. The AMD Ryzen 7 5705GE, with its 8 cores, 16 threads, and 35 W TDP, targets a different use case: efficient desktop computing on the AM4 platform. Users with an existing AM4 motherboard who prioritize low power draw and upgrade simplicity would favor the AMD option, but the benchmark data strongly favors Intel for sheer performance. The Intel part also holds an advantage in process technology, using a 3 nm node versus the AMD's 7 nm, which explains part of the performance gap.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 5705GE uses the Zen 3 architecture, codenamed Cezanne, built on a 7 nm process at TSMC. It packs 10,700 million transistors into a 180 mm² die. The Intel Core Ultra 5 338H uses the Panther Lake architecture, built on Intel's own 3 nm process. The Intel chip lacks published transistor and die size figures in the database, but its architecture is newer and denser.

Core counts differ significantly. The AMD part has 8 cores and 16 threads, relying on simultaneous multithreading to double its thread count. The Intel part has 12 cores and 12 threads, with no multithreading support listed. This means the Intel chip has 50% more physical cores but 25% fewer threads. For workloads that scale with physical cores, the Intel part should excel; for workloads that benefit from thread oversubscription, the AMD part's extra threads may help.

Cache layouts diverge sharply. The AMD Ryzen 7 5705GE uses 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Intel Core Ultra 5 338H uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has roughly three times the L1 per core and five times the L2 per core, which reduces latency for frequently accessed data. Its L3 is 2 MB larger, though shared across 12 cores rather than 8.

Memory support also differs. The AMD part uses DDR4 with dual-channel memory and a 51.2 GB/s bandwidth. The Intel part uses LPDDR5X with dual-channel memory and a 136.5 GB/s bandwidth, which is 2.7 times higher. This bandwidth advantage directly impacts memory-sensitive workloads like data compression and encryption. PCIe connectivity differs as well: the AMD part offers Gen 3 with 16 lanes, while the Intel part offers Gen 5 with 4 lanes. The Intel lanes are faster per lane, but the AMD part has more of them.

Integrated graphics differ in name and capability. The AMD part uses Radeon Graphics with 512 shader processors, while the Intel part uses Arc B370. The database provides no direct graphics benchmarks, so any comparison there remains qualitative.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two processors. However, the Intel Core Ultra 5 338H has a full set of recorded benchmark scores, while the AMD Ryzen 7 5705GE has none. This means the comparison must rely on the Intel part's absolute scores and its percentile ranking versus all CPUs.

For the Intel Core Ultra 5 338H, the Cinebench R23 multi-core score is 16,331, and the single-core score is 2,044. The Cinebench R20 multi-core score is 10,213, and single-core is 1,441. The Cinebench R15 multi-core score is 2,504, and single-core is 305. These scores place the chip in the 84th percentile, meaning it outperforms the vast majority of CPUs in the database. The nearest rivals confirm this positioning: the Core Ultra 7 165H scores 34,083 (0.3% higher), the Core i7-12800HX scores 33,875 (0.3% lower), the Xeon 6353P scores 33,844 (0.4% lower), and the EPYC 4244P scores 34,220 (0.7% higher). The Intel part sits comfortably in the middle of this group, suggesting consistent performance across varied architectures.

PassMark results for the Intel part show strong multi-threaded performance: a multithread score of 28,717, a single-thread score of 4,180, and a physics score of 2,697. Data compression scores 276,539, data encryption scores 21,367, and extended instructions score 23,906. Integer math scores 64,934, floating point math scores 84,067, and prime number finding scores 304. Random string sorting scores 34,082. These numbers indicate a balanced processor with particular strength in floating-point operations and data compression, likely aided by the high memory bandwidth and large caches.

Without any benchmarks for the AMD part, the data cannot show where it wins or loses numerically. The only quantitative comparison available is the percentile ranking: 50th for AMD versus 84th for Intel. This suggests the AMD part sits at the median of all CPUs, while the Intel part sits well above it.

Where Each One Wins

The Intel Core Ultra 5 338H wins in every recorded benchmark category, simply because no benchmark data exists for the AMD part. The Intel chip's 84th percentile ranking versus the AMD chip's 50th percentile provides the clearest signal of overall superiority. The Intel part's 12 physical cores and 18 MB of L3 cache give it an edge in multi-threaded workloads like video encoding, compilation, and scientific simulations. Its 136.5 GB/s memory bandwidth accelerates data-heavy tasks, as evidenced by the strong PassMark data compression score of 276,539 and floating point math score of 84,067. The lower 25 W TDP also makes it more suitable for thin-and-light mobile designs.

The AMD Ryzen 7 5705GE wins on platform flexibility and thread count. Its 16 threads exceed the Intel part's 12, which can help in highly threaded workloads that respond to oversubscription. The unlocked multiplier allows manual overclocking on AM4 motherboards, something the locked Intel part cannot offer. The AMD part also uses the mature AM4 socket, which is widely available in existing systems, and its 51.2 GB/s DDR4 bandwidth, while lower, is sufficient for many desktop tasks. The 35 W TDP is higher than the Intel part but still modest for a desktop processor.

For users building a new high-performance mobile system, the Intel Core Ultra 5 338H is the data-backed choice. For users upgrading an existing AM4 desktop with a low-power, overclockable part, the AMD Ryzen 7 5705GE serves that specific need, though its performance relative to the Intel chip cannot be quantified from the available measurements.
